Campylobacter spp. whole-genome sequencing–based surveillance by country and source in study of multisectoral emergence of multidrug-resistant Campylobacter coli sequence type 10042 lineage, Europe, 2018–2025*

Country (sector) Campylobacter WGS surveillance and coverage
Ireland (human)
 WGS-based surveillance since February 2019. Approximately 10% of national Campylobacter cases sequenced annually; ≈10% of sequenced isolates are C. coli.
Luxembourg (human, animal, food)
 WGS-based surveillance since 2013. 100% of isolates are sequenced.
Netherlands (human)
 WGS-based surveillance since May 2021. ≈400–500 isolates selected annually; ≈90% of sequenced isolates are C. jejuni and ≈10% are C. coli.
Netherlands (animal, food)
 No routine WGS. Sequencing performed on subsets since 2000. During 2021–2022 monitoring, 549 C. jejuni and 960 C. coli isolates were recovered, 540 were sequenced.
Germany (human)
 WGS-based surveillance since 2019. 100% of isolates are sequenced.
France (human)
 WGS-based surveillance since 2024. ≈50% of received C. coli are sequenced.
Portugal (human)
 WGS-based surveillance since 2022. 90% of C. coli isolates are sequenced.
Portugal (animal, food) No routine WGS. Sequencing performed on subsets.

*WGS, whole-genome sequencing.
